The synaptic Xorg driver in being superseded by the newer libinput driver, which can provide lower-level access to multi touch events to clients, but is currently lacking some features found in the older driver.

You can make the synaptics driver take precedence over libinput by copying /usr/share/X11/xorg.conf.d/50-synaptics.conf into /etc/X11/xorg.conf.d, so as to make it take precendence over the libinput configuration file found at /usr/share/X11/xorg.conf.d/90-libinput.conf.

Hope this helps,Monsie
